Product Details

The JE Pistons 194340 forged piston set delivers race-proven performance for high-performance engine builds. Manufactured from 2618 aluminum alloy for superior strength and heat resistance, these pistons feature a 23-degree flat top design with a 4.165-inch bore diameter, 1.000-inch compression distance, and 0.927-inch pin diameter.

Key Features:

  • Application-specific forgings for optimized, uniform crown thickness
  • Contact reduction groove to minimize frictional drag and increase power
  • Accumulator groove for enhanced top ring stability and sealing
  • CNC-machined side relief with lower support band for additional skirt strength
  • Honed pin bores with double pressure-fed pin oilers for improved lubrication
  • Oil rail support included for enhanced ring seal durability
  • Wire locks included with each piston

This complete set includes 8 matched pistons engineered for consistent performance across all cylinders. JE Pistons recommends ring set J10008-4165-5 for optimal fit and sealing. Backed by over 60 years of racing piston manufacturing expertise, JE Pistons are trusted by professional engine builders and performance enthusiasts for Chevy, Ford, Mopar, and Buick applications.
